Check the task, the product and your credits.
If a new product did not get meta tags automatically, check each condition.
- Task: a task with auto-processing on must be Processing, Completed or Completed with errors, with Auto Update showing Products only.
- Scope: for collection tasks, the product must be in one of the collections when it is created.
- Images: the product needs at least one image without alt text. Products created without images are skipped.
